If you've just been given your reading list for for school or college don't forget that you can download audiobooks from itunes for about $15 a pop.
Other things you might want to consider:
1.Check to see if your school or college disability unit can help you. Maybe they loan out ipods and/or can buy the book?
2. At Costco you can buy a $50 itunes card for $45 (you save $5).
3. Maybe someone who likes you will buy you an itunes gift voucher (since this is an educational need).
